My girlfriend (ex now) slept with the sister’s husband. Didn’t know how to feel at first, the sister wants to kill herself. I hate her now, just can’t look at her the same way again, she wouldn’t have told me if the sister didn’t find out. It wasn’t even once. Broke up with her but never got myself till this morning. I feel free and happy now. Just want to relax and be taken care of now, not ready for any relationship anymore.
